The constitution, types and computational theory of composite trusses were described. The advantages and application prospects in the civil industry were focused on. Based on the related references, the muhiplicate process for composite staffs of trusses was expounded and effect of different section shape on the properties of the bars was compared. The damage mechanism and analysis methods of composite staffs were discussed. Types and respective characteristics of joints were introduced and the key problem of joints and connection parts were proposed. According to existing overseas and domestic studies and applications of composite trusses, the properties and different designing methods were presented. The key factors on the properties of the composite trusses and some problem existing in the composite truss design were summarized. Simultaneously, how to improve the design of the staffs and the truss joints and how to optimize the composite truss were suggested.
